Specification forming part. of Letters Patent No. 47,787, dated May 23, 1865.

To all whom, it may concern;

Be it known that I, HERMAN BERG, of Union Hill, in the county of Bergen and State ot' New Jersey, have invented a new and Improved Gas Burner; and l do hereby declare section of this invention, the line w x, Fig. 2,

indicating the plane of section. Fig. 2 is a horizont-al section of the same,l taken in the plane indicated by the line y y, Fig. l. Fig. 3 is a similar section taken in the plane indicated by the line z c, Fig. l.

Similar letters of reference indicate like parts. W'

The object of this inventionV is an improvement in that class of gas-burners in which the supply of gas to the tip regulates itself according to-the pressure ofthegas.

The invention consists in the application to the body of the burner of a chamber fitted with pulverized carbon, or other absorbent and purifying material, and closed on topqby a perforated metal plate and on bottom by a horizontal partition provided with an aperture and with a spring-valve in such a manner that by the pressure of the gas itself the spring-valve is more or less closed and the supply of gas to the tip rendered self-regulating, and that the gas before itis allowed to reach to the tip has to pass through the purifying material, which retains all condensible impurities, and a steady even iiame is obtained.

A represents the tip of 'my burner, which may be made of brass or lany other suitable material. It screws into the body B, which is provided at its bottom end with an internal screw-thread, c, to t to the gas-pipe in the usual manner. Said body is made in two `small holes, or itmay be made of a piece of wire-gauze, so as to prevent the carbon or other absorbent material from passing up in the tip. The lower partition, d, is perforated with an aperture, f, and secured to its undtr surface is 'a thin metal plate, g, which forms a spring-valve capable of closing almost, but `not quite, the aperture f. The elastic force of this spring-valve is so regulated that it closes when the pressure of the gas exceeds a certain limit, and the aperture f in the'partitien d is thus more or less closed, according, to the greater or smaller pressure of the gas. When the spring-valve is forced close up to the under surface of the partition d, a very small opening onlyis left for the passageof the gas, but in this case the pressure of the gas is high and a sufficient quantity passes through to supply the fiame. ln reaching the chamber ethe gas has to pass through the absorbent HERMANN BERG.
